`cargo clippy` does not process build scripts

[FaultyRAM]

cargo clippy doesn't do any extra handling of build scripts beyond what cargo check does. For example, this code will trigger an unknown_lints warning when using cargo clippy:

#![forbid(print_literal)]

fn main() {
    println!("{}", "");
}

Built-in lints still work; adding a #![forbid(missing_docs)] to the above snippet fails the build as expected. clippy-as-a-plugin also works:

#![feature(plugin)]
#![plugin(clippy)]
#![forbid(print_literal)]

fn main() {
    println!("{}", "");
}

I'm not actually sure whether clippy or cargo is at fault here, but since the plugin interface is about to go I figured it might be more prudent to report here first.

I'm currently working on tool_lints (rust-lang/rust#44690), which will allow to just write #![forbid(clippy::print_literal)]. This should solve this problem.

@flip1995 I noticed this issue has no tags. Does that mean it is not prioritized?

No. Not all issues fit cleanly in the labeled buckets.

This in particular is something that would require #3837 to be finished
